Besides the often used and well-known top level domains there are other
domain types, which are reserved for rather small, specific minorities
and can only be registered by them. The usage, however, is available to
everyone, e.g. by accessing a website.

These particular domains cannot be registered by registrars and therefore
cannot be registered by Knipp. But we can assist you with the registration
if necessary. However, precondition is that you are authorized to register
these domains.
